NOTE: To determine if this charger is suitable for your application, you must perform this calculation to determine the maximum amp rate the charger can supply. Divide the Watts of the charger by the Voltage of the battery pack. This will tell you the maximum amp rate the charger can deliver (Watts / Voltage = Amps). So using the Touch 680 AC as an example and a 6S LiPo battery pack, would be 80 Watts divided by 22.2 Volts, which equals 3.6 Amps. This means that the charger can supply a maximum of 3.6 amps to a 22.2 Volt 6S battery. This amp rate will gradually reduce as the battery voltage increases during the charge cycle.

IMPORTANT:
1) DO NOT leave the battery in your model when charging
2) DO NOT leave unattended when charging
3) ALWAYS balance charge the battery
4) ALWAYS use a LiPo charging bag
5) YOU MUST use a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
6) YOU MUST not over discharge the Li-Poly battery pack
7) READ & UNDERSTAND the instructions carefully before operating this battery

Purchased this balance charger for the 80watts power, the touch screen and the ability to read internal resistance. Overall it is a good charger, easy to navigate, bright screen and nice size and appearence. It is weird that although in the manual states that the storage voltage for the LiPo batteries is 3,85 volts (like all other chargers), it is set at 3,90 volts and it doesn't let me set it any lower. It only goes up (way up, over 4,20 volts), but no lower than 3,90 volts. I don't know why, but it is defenatly something that needs to be looked, unless i do something wrong. Also the internal resistance numbers vary from one messurement to another messurment even if you do it multiple times one right after the other. I guess, it is there to give just an indication approximetly of the resistance. I don't know how this feature works on other chargers, this is the first one of mine to measure internal resistance. Still nice thing to know the condition of the battery.)

I had no RC experience and only started to play since 2014, this charger is my first one, so I can't tell you the comparison with others. But this charger is good for me, I didn't know how to start to charger until I found out I had to press for 5 seconds to see the start button. This thing is light for me to carry around, price is not to bad, so I think for newbie this is not bad.)

I Picked this Charger Up For the Price...Got it on a Saturday Morning Used it @ a Race on Sunday to charge up my Dynamite Reaction 6000Mah 80C 4S Lipo Pack's... @ first look I thought I don't know how good this Charger would perform under Race Conditions & Constant Charging of Packs Between Rounds "Because it is not Rated as a RACING CHARGER in the SPEC's... But My worries where over as soon as they started.. This ProTek Charger performed without a hitch Kept my Packs @ a Full Charge & Full Per Cell Count Voltage as well each time I Volt tested my packs... The touch screen is very easy to navigate / Charger is very simple to use / The onboard cooling Fan keeps the Unit fairly cool during Charging "did not have to use an external Fan for cooling like some of my fellow Off-Road Racers are seen doing with there Chargers" / & is a must on race day to have a Charger that is easy to use & holds up to the rigors of a Race Day...Would recommend picking up this Charger as I did as a Second Charger Weather your a Racer "Like myself" or a Backyard Basher...)

This is a great little charger for the money. The touch screen and interface is really easy to navigate and set up. The included balance board is a little short, but you get lots of different charge leads for just about any type of battery you wish to charge. The size is really nice as well. It is compact and does not take up a lot of space on my pit table. I use mine to charge my starter box and RX lipos for nitro and it works great doing that. If you are looking for a great charger at a low price and you don't need to charge multiple batteries at once, this is just awesome. 5/5 Love it!!!!)

this charger is awesome. does a great job with not much fuss. if you are like me and don't have much experience with charging lipo batteries, you may find the instructions are really vague and not very confidence inspiring. but i found a myriad of source material on the subject online. https://rogershobbycenter.com/lipoguide/ this one in particular was very helpful)

I've had my charger for some time now and this has been a great charger. Very easy to use, with a small footprint for my pit space at the track. It comes with the stylist but I've had no need for it. It works great with just my big fingers (size13 work gloves). The options for charging are easy to use and I would recommend this charger for any racer or basher.)

This charger is great, love that it has 80w, can charge my 2s 4500 mah lipos in about 30min at 2c rate. My only gripe with this charger is that it only has memory for 1 battery, so if you have multiple packs of different Mah and cell counts, then you would have to manually enter those specs every time you charge a different batter pack. Other than that its an awesome charger, really loving the Protek brand, My lipos, servos and now my charger are all protek and haven't had any issues.)

Great charger for the price. I had a few unbalanced batteries and with this charger they are all back to 100% working order. Stays around 75-80 degrees constantly. I've had this thing going for 3 hours or so with no hot temps. Always remember your LiPo bag!)

Great charger for the money. Very easy to use and the backlit display makes everything very easy to read. It comes with a stylus which is a plus but I use my fingers which works just as well. Also included is charger leads for various plugs which is really great to have around if you have batteries with different style connectors. All this backed up by A Main's great service and you really can't go wrong.

I wish there was a switch to turn the unit on and off instead of unplugging/replugging the power cable but this is me just nit picking. I fly helicopters now, so this was the perfect charger for me. Back when I was racing R/C cars, I would have purchased the Duo or even Quad charger.)

This was my first "professional" quality charger. Up until now I had always used the charges included with the various craft I've purchased. I didn't know what I was missing! The various modes allow me to do just about anything I'd like (e.g. fully charge, charge for storage, discharge, etc.) and the on-screen controls are very intuitive. My only complaint (and a *very* minor one) is that it didn't come with a charge cable with an EC3 connector. I bought one from my LHS for $6, but it would have been nice to get one with the charger. All in all, this was an excellent addition to my tool chest.)

Great charger, plenty of power for parallel charging UMX batteries with the Protek 2 cell 12 battery and the 1 cell 12 battery boards. The internal resistance meter is cool and you can monitor individual cell voltages.)

I use this to charge my gens ace 2s 5000mah batteries and it does an amazing job! I'm getting almost 40 minutes per battery. It needs an ON/OFF switch....dumbest thing I've ever seen NOT having an ON/OFF switch..forces you to plug IN/OUT each time.)

Just got it a few days ago..... it's smaller than I imagined. But it's very cool!! I like it alot though. It's quiet and very easy to understand. I'm still stuck in the NimH age but at least now I can start updating my batteries. Thanks Amain!!

UPDATE: 9/30/16
Charger is still a great value.... however... the main battery charge lead WILL fall apart on you. It's a cheap Chinese product with TINY 22ga wires that barely hang on to the Deans plug. I get it. Keep costs down.... but this is the main power going to the battery. After re-soldering the Deans plug back on three times, I had enough and took it completely apart. I saved the banana plugs and the Deans plug then used Deans Wet Noodle 12ga copper wire between. Now it's 100x stronger and I feel confident that it can carry the amperage load. This is the only fault I've found in the package. Everything else (so far) has held up.)

this product is very easy to use and practical, easy to understand and versatile. only thing is when you charge a brand new battery, don't use the auto option, as it won't fully charge the battery. Other than that I would recommend it to anyone!)
